However, we will add the new names to the in-program (and hence wiki) database so that this new information becomes public. Thanks for the heads up, Victor. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

[announce] flashrom 1.0.1-rc1

by Nico Huber

Hi flashrom fellows, I've just tagged `v1.0.1-rc1`. This is only a bug-fix release, obviously the first on our 1.0.x branch. The latest commit is rather new, so please test! Especially your layout use cases. During the past year, we've gathered a total of 6 fixes! Namely: * 6b9e934f linux_spi: Reduce maximum read chunksize Improves compatibility with older Linux kernels that interpreted the interface differently. * 30c4cecd Makefile: Disable `-Werror=deprecated-declarations` on release branch Just to be able to compile the 1.0.x branch on newer systems. * 5639af64 linux_spi: Hardcode default spispeed of 2MHz Default speed of kernel drivers isn't always sane (any more). * 993e162d dediprog: Fix small, unaligned reads An actual bug, discovered during experiments with arbitrary layouts. * ec8b8a7f board_enable.c: Fix dmi_match string for ThinkPad X201 Probably just wasn't tested before. * 69f96f60 Fix verification with sparse layouts A regression that sneaked into flashrom-1.0: When verifying the whole flash after a partial write with a sparse layout (i.e. a layout whose regions don't cover the whole chip), flashrom tried to verify against the wrong data and failed. Again, please test. If you don't use Git, you can find a tarball here: https://review.coreboot.org/cgit/flashrom.git/snapshot/flashrom-1.0.1-rc1.t… It still passes all my local build tests, see below for a full list.

Using Meson to build flashrom

by Richard Hughes

Hi all, First, happy new year and I hope you all had a great break. As some of you know, I've been working with 3mdeb for the last few months, with the aim of using libflashrom in fwupd to be able to flash firmware using the LVFS on various embedded systems. This /could/ include flashrom-compatible consumer hardware in the future, although I've not worked out all the details on how something like coreboot-on-thinkpad could be distributed automatically. Anyway, I digress. The fwupd project has to build in all kinds of odd targets, e.g. for odd endians, odd instruction sets, and in odd ways, e.g. installing with a prefix of /app for projects like flatpak. We also have other "robustness" guarantees and therefore have a comprehensive set of CI tests which enable a lot of warning flags and run linting and static analysis code like Coverity. This might explain my ongoing effort to fix up seemingly benign warnings. Rather than hack the hell out of Makefile (which I started to do initially) I ported the codebase to use the meson build-system. Meson is a(nother) next-generation build system used by a lot of open source projects ranging from low level libraries to desktop software. As part of the port, I also copied the CONFIG_ logic from the makefile, e.g. Option Current Value Possible Values Description ------ ------------- --------------- ----------- config_atahpt false [true, false] Highpoint (HPT) ATA/RAID controllers config_atapromise false [true, false] Promise ATA controller config_atavia true [true, false] VIA VT6421A LPC memory ... At the moment I'm using the meson port so I can include flashrom as a subproject to fwupd (as distros are not yet shipping libflashrom as a proper shared library) but 3mdeb is some way from being finished with libflashrom. I wondered if my work would be useful already to anyone else building flashrom on weird embedded architectures, or of it would be interesting to upstream with further work. The single commit which just adds 5 files can be found here: https://github.com/hughsie/flashrom/tree/wip/hughsie/meson Comments welcome. Richard.

flashrom, and 4-byte addressing SPI (example: MX25L25635E)

by Евгений

Good day. MacOS+Homebrew+flashrom. Flashrom does not understand 4 byte addressing (chips > 16MB). With 3 byte addressing work perfectly (chips <= 16MB). May you add 4 byte addressing for SPI flash? Example MX25L25635E - 32MB uses in different new routers. CH341 in Windows work with 4 byte and read/write flash and registers from this SPI flash: JEDEC ID(9F) = 0xC22019 RES ID(AB) = 0x001818 REMS ID(90) = 0x00C218 Sreg: 00000000(0x00), 11111111(0xFF), 00000111(0x07) but on MacOS not software that can do it.

flash chips not supported - modify config file?

by Hugo.Bitard

Hello, First of all, i would tell you that you do an amazing work with flashrom. It is really awsome!! I would like to dump the firmware of an Atmel 24C01A, but this flash chips is not a supported one. I found 2 files, that could be of interest: flashchips.c and flashchips.h, but i do not know how to modify it in order to support the Atmel 24C01A chips. If you could give me some advice about the procedure, it could be very helpful. Thank in advance Best regards Hugo message envoyé depuis ProtonMail

Re: [flashrom] [coreboot] [LinuxBoot] FOSDEM 2019 deadline today

by Carl-Daniel Hailfinger

In that case, I'd also like to point you to the deadline for submitting main track talks which is tomorrow(!). https://fosdem.org/2019/news/2018-08-10-call-for-participation/ Having a coreboot/LinuxBoot talk there would be awesome. Ron/David, could you submit something or do you have someone in mind who can do that? There's also lightning talks, deadline is a bit later. OK, I'm submitting a request for a stand. I need a backup contact for the stand. Who is willing to do that? AFAICS we can still change the backup contact later if life happens.
